All other existing thymus products are not biologically active, because they contain only fragments of the entire thymic protein necessary to stimulate T-4 cells. Fragmented proteins will not "fit" into the receptor site of the T-4 cell, and therefore will not program it as ProBoost does. No other thymus extract or product is comparable to this unique protein. It is so unique that the doctor who developed this product has been awarded a US patent.
